When you remove the drum and look at the shoes inside, you'll see two arms going to the top of the shoes, one each side. they're not attached to the cylinder, they come from the back of the drum. make sure these are in place on both sides, if not then the will be no force on the shoes from the handbrake causing it to feel weak, as theyre is not enough grip. if this is the case, once fitted in place you should notice a significant difference. If they are both in place, the splitter may have come loose when you originally did the shoes and removed the arms. it usually fits just infront of the fuel tank.
